“…Also unlike the previous study, avoidance was only found to mediate the relationship between TE and use of over-exercise to control weight in men, however this may be due to the fact that Holzer et al (2008) investigated social avoidance whereas the current study examined avoidance of reminders of a traumatic or stressful experience (both internal and external avoidance as per the DSM-5 C1 and C2 symptom criteria). In contrast, dissociation, a symptom category not investigated by Holzer et al, was found to be a significant mediator in the relationship between TE and EAT-26 scores as well as between TE and a number of ED symptoms: binge eating (men and women), restricting (men), intentional vomiting (men and women), use of medications to control weight (men) and use of over-exercise to control weight (men).…”

“…Further, PTSD symptom categories of re-experiencing, avoidance and dissociation will be investigated as multiple partial mediators of the predicted association between TE and ED symptoms separately in women and men. Based on results from previous research (Holzer et al, 2008), it is expected that avoidance will be a significant mediator whereas re-experiencing will not. Also based on previous research, and that dissociative experiences are commonly associated with both ED and PTSD, and often strongly predict psychiatric comorbidity (Brewerton, 2007), dissociation is also expected to be a significant mediator.…”

“…Lack of insight regarding causal relationships between symptoms was a noted limitation in the study by Holzer et al (2008). In addition to investigating the relationships between frequency ratings, PCR explores the nature of subjective ratings of relationships between symptoms.…”

“…For example, Holzer, Uppala, Wonderlich, Crosby & Simonich (2008) explored the mediation significance of PTSD in the relationship of sexual trauma and ED in four groups of women (n = 97): (1) history of childhood sexual abuse, (2) history of rape in adulthood, (3) history of childhood sexual abuse and rape in adulthood, (4) no history or sexual abuse or assault. They found that a history of any sexual trauma was associated with increased ED psychopathology and increased PTSD symptomatology.…”

Posttraumatic stress disorder (PTSD) and eating disorders (ED) are frequently comorbid psychological conditions in persons who have experienced traumatic life events. This thesis investigates a gendered analysis of the co-occurrence of symptoms of ED, PTSD, and dissociation using Perceived Causal Relations (PCR) scaling in a convenience sample recruited online (n = 523) as well as in persons seeking inpatient treatment for ED (n = 12). Within the internet community sample, re-experiencing, avoidance and dissociative experiences were found to mediate the relationship between trauma history and ED symptoms in men and women.Although dissociation was a consistent mediator in this relationship, it was not perceived as a significantly greater cause of ED-related behaviours than vice versa on PCR. Within the clinical sample, ED-related behaviours were often perceived as effects of trauma-related, anxiety and mood symptoms. The implications of these results for understanding the comorbidity of ED and trauma-related symptoms are discussed.
